APPARATUS FOR COOLING AND VENTILATING.

SPECIFICATION formingpart of Letters Patent N 0. 690,485, dated January 7, 1902.

Application filed May 1, 1901. Serial N0.58,249. (No model.)

To aZZ whom it may concern:

Be it known that we, JOHN TITUS, a resident of Oyster Bay, and WILLIAM TITUs, a resident of Old Westbury, in the county of Nassau and State of New York, citizens of the United States, have invented certain new and useful Improvements in Apparatus for Cooling-and Ventilating; and we do hereby declare that the following is a full, clear, and

so exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which Figure 1 is a diagrammatic View showing certain combinations and arrangements of :5 parts included in our invention. Fig. 2 is a detail horizontal sectional view still further illustrating our said invention.

. This invention is designed for use in dwellings, hospitals, apartment-houses, and other an structures in which effective ventilation with more or less refrigerated air is desirable.

- It comprises certain new and useful combinations of parts wherebycooled air orcooled air combined with air of normal temperature to any desired degree may be provided to a room or suite of rooms or within structures of any suitable kind.

A indicates stories of a house or structure of any suitable kind. Extended upward to 3c the requisite height, whether one or more stories of the structure, is a cold-air tube or shaft B, which at its upper part terminates in a refrigerating-chamber O. This chamber may be furnished with any suitable means for 33 cooling air which is passed into and through the same. As shown in the drawings, Fig. 1, a simple ice-box placed in a loft above the rooms to be ventilated or cooled,with the coldair shaft extended downward from the bot- 40 tom of said box, is employed. As various and differing means of cooling air passed through a refrigerating box or chamber are known in the art of refrigeration, the same call for no specific description here. In the 5 cold-air shaft 13, preferably one or more at each story to be ventilated, cooled, or regulated in temperature, is a register D for admittin g a regulated quantity of air to the ad jacent room or place to be cooled by refrigerated air from said shaft.

These registers may be of any preferred or suitable construction; but, as shown in the drawings, Fig. 1, they are of the circular variety, turning upon an axial pivot and each provided with a radial arm a, Wherebymovement may be given to the movable part of the register to enlarge or diminish the outlet t-herethrough to increase or diminish the outflow of air therefrom, as occasion may require. As registers ofthisandotherconstructionsarewellknown, no specific description thereof seems to be here required.

Placed in due relation with the cold-air shaft B is an air-pipe E, which at its upper end connects with the refrigerating-chamber O in such a manner that air issuing from said upper end of the pipe is cooled by or during its passage through the chamber. Provided in the air-pipe E, to propel atmospheric air therethrough to and into the refrigerating- 7o chamber 0, is a fan-blower or other air-forcing mechanism F. From the refrigeratingchamber the air descends through the airshaft 13 to the register thereof, where it may issue to the adjacent room or apartment A. In the air-pipe E, properly adjacent to each register D thereof, isa corresponding register G, the office of which is to permit air at, say, normal temperatures in regulated quantities to issue from the air-pipe E into the ad- 8o joining room or apartment of the structure to be ventilated. Each register G of the airpipe should be placed in such juxtaposition with a register D -of the cold-air shaft that motion communicated to one of said registers may be simultaneously transmitted to the other. This may be conveniently provided for by means of a connecting-rod'b, which extends from the outer part of the arm CL of one register to the corresponding part of the arm 0 a, of the other. It is preferred that this rod be made detachable, so that the two registers may be independently manipulated When exceptional circumstances require. Provided in each room A is a thermostat H, the 'free 5 end 0 of. which connects by a rod 01 with one of the arms a of one of the registers, so that movements of said free end of the thermostat will automatically actuate the two registers in unison. As shown in the drawings, the

thermostat is of the well-known construction, composed of two united burred strips of metal having different ratios of expansion from heat; but the variety of thermostat to be employed is a matter of choice, and the devices for transmitting movement therefrom to the registersone or bothmay be varied within wide limits. The precise means for transmitting such motion is of no moment so long as they effect the requisite movements of the register or registers from the operation of the thermostat. A damper e may be provided in the cold-air shaft to throttle the passage of air therethrough when desired, and a similar damperf may be provided for a like purpose in the air-pipe. To provide for distribution from the cooled-air shaft and the air-pipe to points more or less remote from the registers, the latter may have conduit-pipes g 77. extended therefrom, as shown in Fig. 2, to conduct the air, and when desired these conduit-pipes may connect with a distributingtrunk I, in which may be a damper h to retard, if occasion demands, the flow of air therethrough.

The operation of the apparatus is as follows: The refrigerating-chamber 0 being supplied with ice, as indicated at 71, or otherwise arranged to refrigerate, as hereinbefore explained, and the blower F being set in operation to force a current of atmospheric air upward through the air-pipe, a portion of said air enters the refrigerating-chamber and being there cooled or refrigerated descends therefrom into and through the cold-air shaft tothe registersthereof. Simultaneouslywith this a portion of the air forced upward in the air-pipe passes out through the registers of the latter, so that there is a simultaneous discharge in immediate connection with each other of a current or currents of air at normal temperature from the air-pipe and a current or currents of cooled air from the airshaft in such relation with each other that the cold air practically tempers the other,and vice versa, so that any desired degree of coolness in the room or apartment A may be obtained by a perfectly regulated proportion between the inflows of air from the air-pipe and the cold-air shaft. The proportion of air propelled through the registers of the air-pipe may be controlled by the damper f, which may be turned or adjusted to offer sufficient resistance to the current through the air-pipe and yet supply air in suflicient quantity to the refrigerating-chamber for the purpose described. The rapidity of descent of the cooled air through the cold-air shaft mayin a similar manner be adjusted by the damper e therein.

The registers of the air-pipe being connected with the adjacent register of the cooledair shaft and both being connected with a thermostat, as described, the latter may be readily adjusted to operate at a predeter mined temperature in the room or apartment A to simultaneously actuate the two registers to admit the requisite proportions of air at normal temperature from the air-pipe and cooled or refrigerated air from the cooled-air shaft. p

It will be observed that when the temperate and the chilled air meet in the tube or conduit I (shown in Fig. 2) they mingle and mutually react so that the temperature of the airin said conduit, at the outlet or place of delivery of said air, is below that of the air from the shaft E and above that of the air from the cold-air shaft B, the desired temperature of the volume of air delivered from the conduit I being obtained by adjusting the various relative proportions of temperate and chilled air passed into the conduit I from the two shafts E and B, the conduit I constituting, so to speak, a mixing-chamber located between the shafts E and B and the outlet of the mingled volumes place or apartment to which the tempered air is to be delivered.
